+# ./darcs-all [-q] [-s] [--nofib] [--testsuite] get [darcs get flags]
 #   This gets the GHC core repos, if they do not already exist.
 #   -q says to be quite, and -s to be silent.
-#   -i says to ignore darcs errors and move on to the next repository
-#   -r repo says to use repo as the location of package repositories
 #   --nofib, --testsuite also get the nofib and testsuite repos respectively
 #   The darcs get flag you are most likely to want is --complete. By
 #   default we pass darcs the --partial flag.

 #   This runs the darcs "cmd" command, with any flags you give, in all
 #   of the repos you have checked out. e.g.
 #       ./darcs-all pull
